Shame on me. I haven’t watched Jack Dorsey present before (live or on video), and I had made certain assumptions about him because of his business success (co-founder of Twitter, founder and CEO of Square) and because he was (in)famous for working full-time at both of them for a bit.

What I especially love about this talk is that towards the end he openly shares the personal development items that he’s working on (his list of Daily Do’s and Daily Don’ts). He has a note on his phone that he checks every morning, periodically during the day, and at night. Here are some of the items on the list:

Daily Do:

Stay present

Be vulnerable

Drink only lemon-water and red wine

Exercise (Squats, Pushups, Planks & Run)

Stand up straight

Say hello to everyone

Do a video journal entry

Get 7 hours of sleep

Daily Don’t:

Don’t avoid eye contact

Don’t be late

Don’t set expectations and fail to meet them

Don’t eat sugar

Don’t drink hard liquor or beer on weekdays

The “be vulnerable” really stuck out for me. It’s a necessary piece for having real relationships outside of work, and for having high-trust relationships within work.

A quick story: In the past I really struggled with what to do about a particular member on my team who wasn’t excelling the way he could, and the issue boiled down to his need to maintain emotional barriers between himself and others. My coaching advice was centered around encouraging him to allow himself to be a little more vulnerable. It felt odd at the time to be talking about vulnerability, but now that I have a little more experience I really think that this barrier would impact his career, and that this was sound advice.

So I’m glad to see an extremely accomplished CEO sharing something as touch-feely as the importance of being vulnerable to an audience of aspiring entrepreneurs. And the rest of the items on the lists are great too.
